gdal330編譯

A. 如何使用已編譯好的gdal文件

真搞不明白了,你去這有下載 http://www.gissky.net/Article/643_2.htm 把文章好好看了,其中有編譯好的下載 確認你的BIN目錄下有VCVARS32.BAT文件么

B. 如何在ubuntu使用eclipse 中c++開發環境配置gdal

1.最重要的東西，C++必要工具，讓歷安裝的是GCC工具鏈，Make等一系列開發坦棚搜工具：
sudo apt-get install build-essential
2. 安裝Eclipse
sudo apt-get install eclipse
sudo apt-get install eclipse-pde
sudo apt-get install eclipse-jdt
3.打開Eclipse,打開Help->Install New Software,然後點擊Add按鈕,在彈出的對話框中
Name項填入CDT
Location項填入http:// download.eclipse.org/tools/cdt/releases/indigo
點擊Ok按鈕,在下邊出現的列表中,
第一個CDT Main Features基本都要安裝
第二個中務必要把包含GNU字眼選擇安裝(這一步因為老是出現依賴錯誤，我就乾脆先不裝了，以後用到再說)
4 .配置Autotools支持
基本上同第四步一致:
Name項填入Autotools
Localtion項輸入:http:// download.eclipse.org/technology/linuxtools/update
點擊Ok按鈕,在下邊出現的列表中,將此選項選中,然後安裝即可
Autotools support for CDT (Incubation) 3.0.0.201106060936
5.可以在eclipse中玩轉vim
直接從eclipse安裝即可，地址：http:// vrapper.sourceforge.net/update-site/stable/

裝完重啟eclipse後在菜單藍出現gvim圖標
6.下面是編譯執行c ++項目時的一些設置：
項目包含外部頭文件，將頭文件路徑導入：

項目需要外部動態鏈接庫(-L)：

指定程序運行和慶時路徑(-R)：

C. Linux（centos8）系統安裝編譯GDAL 2.2.1

win10系統安裝gdal，看這篇： windows 安裝 GDAL - (jianshu.com)

GDAL庫是處理地理信息一個非常強大的庫，我這邊要用它做 cad 轉 geojson 的工作。測試是在windows上進行的，然後現在需要部署到linux上，遇到了安裝上的坎兒，記錄一下。

DownloadSource – GDAL (osgeo.org)
可以直接：

python36-devel 找不到的話 用：python-devel

在make編譯這一步，我報了個錯誤：
jpeg2000dataset.cpp:35:10: fatal error: jasper/jasper.h: No such file or directory

jasper安裝完之後，重新執行步驟4（4. 執行配置、編譯、安裝：）

在最後添加如下：

保存：

應用：

這步不執行會報錯：報錯：gdalinfo: error while loading shared libraries: libgdal.so.20: cannot open shared object file: No such file or directory
找不到共享庫，意思就是在 bashrc 中添加的沒生效。
解決：參考： https://..com/question/1929349307136401747.html

D. 如何將debug版本的so庫變成release版本

由於Smart_Gis安卓客戶端的需要，所以需要把gdal_2.3.1庫編譯成安卓平台Arm64_v8a版本的.so庫。由於要求是android NDK版本 12以上，Android API 21以上的支持。

所以在本次編譯過程中全部需要使用64位的操作系統，NDK及編譯器，編譯環境為 操作系統：Ubuntu 16.04 LTS，安卓NDK版本：android-ndk-r14b,geos, proj。

1，最近遇到了之前編譯的geos, proj, skia, gdal庫都為debug版本，本人也沒有特意的去驗證，但是由於項目上線發布的原因，需要將所有的依賴的庫發布成release版本的，一來可以增加庫的穩定性，二來可以減小體積。

2，由於 gdal 庫在編譯成release版本的過程中可以參考我的gdal庫安卓平台編譯這篇文章，並在Application.mk文件裡面增加 APP_OPTIM := release 然後 ndk-build命令進行編譯就行了，如何驗證生成的庫是不是debug版本的呢？

  在庫目錄下執行 readelf -S + 文件名 ，在列印出的信息中如果能查看到有debug字元即是debug版本。

3，到這一步我們需要找到我們打開我們編譯的工具鏈的位置，找到strip這個可執行程序，比如說 GCC存儲目錄或者本人的Android 交叉編譯工具鏈的位置。然後找到存儲.so庫的目錄下並復制當前目錄加上需要裁剪的庫名到工具鏈strip存放目錄下，

如下圖所示並回車。

4，再次查看SO庫並會發現該庫的體積縮小了很多，並使用readelf -S + 庫名列印出來的信息沒有debug字元。

E. gdal for android 如何支持 gpkg

編譯環境如下：

ubuntu 16.04 LTS

android-ndk-r18b

GNU Make 4.1

代碼版本如下：

gdal-2.2.3

curl-7.59.0

按照網上的辦法順利對GDAL進行了交叉編譯，坑來了。

利用GDAL的CPLHTTPFetch測試網路抓取功能的時候，沒抓取到文件。測試函數如下：

bool SaveUrl2File(const char* pszUrl, const char* pszFileName)
{
if (CPLHTTPEnabled() != TRUE)
return false;

CPLHTTPResult *pRest = CPLHTTPFetch(pszUrl, NULL);
if (pRest == NULL)
return false;

FILE *pFile = fopen(pszFileName, "wb");
if (pFile == NULL)
return false;

fwrite(pRest->pabyData, sizeof(GByte), pRest->nDataLen, pFile);
fclose(pFile);

CPLHTTPDestroyResult(pRest);
CPLHTTPCleanup();
return true;
}
查看錯誤信息，大概的意思是需要HTTPS支持，查資料得知，需要在編譯curl的時候指定--with-ssl 才能支持HTTPS，然後就開始編譯openssl庫，本來應該是比較容易的一件事，結果整了足足一天，糟糕的是還沒把ssl編譯出來。我用的NDK版本比較高，編譯器是clang，真是沒搞出來，原因是和NDK版本有密切關系，貌似GCC比較容易，clang是google推薦編譯器。之後就從網上找ssl庫，arm64-v8a的ssl不太好找，還好在GITHUB上找到了。

這是成功在curl中集成ssl後的configure輸出，注意最後一行Protocols 中要出現HTTPS，另外在編譯curl的時候要指定ssl的庫目錄，和庫名字，否則鏈接的時候可能會找不到庫。

export LDFLAGS="-L/xxx/xxx/build64dr/openssl/lib" ，指定ssl庫的搜索目錄

export LIBS="-lssl -lcrypto -lz"，指定ssl庫名字

GDAL編譯好後，開始測試 SaveUrl2File 函數，測試失敗，提示SSL certificate problem: unable to get local issuer certificate，調用CPLSetConfigOption("GDAL_HTTP_UNSAFESSL", "YES");即可解決，原理就不說了。OK，GDAL在android下可以抓取網路數據了。

F. 如何編譯mapserver在windows環境下

編譯mapserver的時候一定要選擇一個根目錄
推薦 C 盤
在C盤下面創建一個projects目錄
將你的所以用來支持mapserver編譯的支持庫文件都放到該目錄下面
註：由於mapserver等都是開源的軟體。但是都有一定的版權。所以他們不是集成到mapserver下面的，而是有各種支持庫文件通過編譯說明文件鏈接
所有文件鏈接的說明文件在nmake.opt文件中。這是使用vc編譯的說明文件。在編譯的時候具體選擇支持什麼庫文件都可以在這里說明。

下面是具體的編譯環境
gdwin32 的bgd.lib是第一次編譯後拷貝過來的運行makemsvcimport.bat
libpng 的libpng.lib，libpngd.lib是第一次編譯後拷貝過來的vc6
freetype 的freetype2110_D.lib在vc7下面編譯成功
zlib zlib.lib 編譯成功在zlib123\contrib\vstudio\vc7用vc7
proj proj.lib 在vc7環境下編譯成功
curl libcurl.lib 在vc6編譯下成功 C:\projects\curl\lib
gdal gdal.lib 用submake.bat批處理文件執行編譯成功
pdflib 用vc7編譯成功 C:\projects\PDFlibLite
fcgi 沒有成功 將fcgi_config_x86.h改為fcgi_config.h用vc6編譯成功
jpeg 沒有編譯成功將gdal里的拷貝過來
regex 沒有編譯成功
編譯支持庫的時候比較艱難
仔細細心的查看各個支持庫中的文檔目錄。一般都會有一個可以通過的編譯。
編譯的時候也要懂得使用技巧。比如他說找不到庫文件或著什麼頭文件或源文件你都可以從其他地方拷貝一個過來。

G. cmake編譯單/多文件

在該路徑下會生成一個文件夾(CMakeFiles)，三個文件(Makefile, CMakeCache.txt, cmake_install.cmake)以及一個程序(addition)

此時的文件目錄結構為

該項目該依賴於MPI，GDAL和cereal庫。MPI和GDAL庫自行編譯

1.配置各種編譯的時候，可以使用set設置，更多詳情，請自行搜索。
2.頭文件的包含請使用include_directories。
3.搜索源文件請使用aux_source_directory。
4.第三脊滾基方庫的查找使用 find_package。例如我們想找GDAL, 那麼 find_package(GDAL), 它會在 /usr/share/cmake/Moles 文件中的FindGDAL.cmake文件中去找GDAL的各種信息。前提是GDAL 是make install的， FindGDAL.cmake中才會有GDAL的各種信息。否則的話，我們需要set自行制定GDAL的相關信息。
5.第三方庫的鏈接用target_link_libraries。
注意，也櫻謹可以將該項目中的某個文件夾編譯成靜態庫，然備隱後在於其餘源文件鏈接，可以參考： https://blog.csdn.net/cliukai/article/details/90670243

簡單的多文件編譯： https://blog.csdn.net/cliukai/article/details/90670243
有第三方庫的文件編譯： https://blog.csdn.net/fb_help/article/details/79593037

H. 使用nmake編譯Gdal源代碼（Win10+VS2022）

為了編譯Gdal-master的源碼，需要PROJ的支持，而PROJ又需要SQLite的支持。

SQLite、PROJ、Gdal-master的源碼及編譯可參見網頁：

https://www.toutiao.com/a7063703225425199623/?log_from=fe233e3892be3_1644664643652

也可使用nmake在命令行創建(參考網頁 https://trac.osgeo.org/gdal/wiki/BuildingOnWindows ）

使用命令行，進入VS2022開發者命令行窗口

cd D:ProgramsMicrosoft Visual

D:

vcvars64.bat

cd D:SourceCodesgdal-master

set BINDIR=d:programsgdalgdal-bin

set DATADIR=d:programsgdalgdal-data

set INCDIR=d:programsgdalgdal-include

set LIBDIR=d:programsgdalgdal-lib

修改文件「nmake.opt」的內容：

（1）將

#PROJ_INCLUDE = -Id:install-projlocalinclude

改為

PROJ_INCLUDE = -ID:My3rdPartyinclude

（2）將

#PROJ_LIBRARY = d:install-projlocallibproj_6_0.lib shell32.lib ole32.lib

改為

PROJ_LIBRARY = D:My3rdPartylibproj.lib shell32.lib ole32.lib

依次使用下列命令， 創建x64的Release版本

nmake -f makefile.vc MSVC_VER=1930 WIN64=1

nmake /f makefile.vc install MSVC_VER=1930 WIN64=yes

nmake /f makefile.vc devinstall MSVC_VER=1930 WIN64=yes

執行完畢後，目錄「d:programsgdal」中的內容如下（使用命令 「tree /f d:programsgdal」 列出)

I. C# GDAL 打開遙感影像圖片

對於遙感來說，1W像素實在不算多。GDAL對你這個問題沒有什麼意義，因為GDAL是用來讀寫圖像文件的，而你的問題是繪制。要繪制影像，以下幾點要考慮到：1）如果只是顯示局部影像，那麼一定要先把這局部數據提取出來；2）如果要在窗口像素超出要顯示的影像像素，那麼要採用金字塔技術，根據像素多少判斷該採用哪個金字塔層，建金字塔的技術有很多，比如最鄰近法（最最簡單的方法）、雙線性插值法、立方卷積法等。最鄰近法因為速度快，你在顯示之前按照原理直接從基礎影像中提取即可，其他方法最好要預先建立。

J. 請問我在vs2010下配置c#的gdal庫

VS2010默認使用鏈晌的是棚畢鋒.NET 4.0框數坦架
XP預裝的是2.0或者3.5
所以會報錯
